Description

Biomeasuring device with built-in weighing scale

This application is a divisional application of Chinese Patent Application No. 01104619.8 (application date: February 16, 2001; title of invention: biological measuring equipment with built-in weight scale).

technical field

The present invention relates to a biometric device for measuring body impedance and for providing body fat percentage or other information useful for health care. More specifically, the present invention relates to a biological measuring device with a built-in weight, which includes a transparent measuring platform.

Background technique

A body fat measuring device with a built-in scale is generally available as a well-known biometric device. This body fat measurement device includes a two-layer structure measurement platform, which has an inner plate and an outer plate. The inner plate of the measuring platform is generally formed from rolled steel plate by pressing process, so that its shape is similar to the lid of a box. The inner plate has sufficient mechanical strength to transmit the weight of the human body without permanent deformation when the person is positioned on the measurement platform.

The outer plate of the measuring platform is usually formed by injection molding of colored plastic resin. The outer panel is also shaped like a box lid and includes several ribs on its inner surface. The outer plate is provided with electrodes formed by a pressing process for measuring biological impedance. The outer plate acts as an insulator between the electrodes. In order for a person to place his feet correctly on the electrodes, the outer plate is provided with some indicative means such as a raised portion as a reference for his heel, or on a piece of paper attached to it. some indicative signs.

In addition, a reflective liquid crystal display with low power consumption is used to indicate the measurement results numerically or graphically.

As mentioned above, a body fat measuring device with a built-in scale is very useful because it can simultaneously measure the body weight required to obtain a body fat percentage.

However, as mentioned above, in body fat measurement equipment, it is common practice to attach a sheet of paper with important information such as precautions or operating illustrate. Therefore, if the paper is attached to the bottom of the device, it is necessary to turn the device top down to read this important information on the paper. On the other hand, if such paper is attached to the upper surface of the outer panel, the paper may be torn off because it is repeatedly stepped on by human feet, especially wet feet of people after taking a bath.

In addition, when the person to be measured is on the outer plate of the measurement platform, it is necessary to look at the indicator marks on the outer plate in order to stand on the electrodes accurately. However, if a person looks at the indicator signs after they are already on the outer panel, it is difficult to find the indicator signs because they are already out of the person's field of vision. Therefore, if the measurement is performed in a dark place such as in a bathroom, a person may be located on the outer plate offset from the electrodes, which may cause errors in the measurement, or, in the worst case, no measurement at all.

In addition, since reflective liquid crystal display devices are designed to require ambient light for quick visible display, such display devices are difficult to see in dark places.

In addition, the display means simply indicates the measurement result numerically or graphically, and therefore, it does not exert a strong influence on the person to be measured. In particular, an obese person does not feel strongly that he is obese after being measured.

Finally, the devices of the prior art also have the disadvantage that they have to be disassembled even in the event of minor faults, for example in the event of a broken wire, in order to search for the fault.

Contents of the invention

In view of the above, the present invention aims to solve the problems in the prior art as described above. More specifically, the object of the present invention is to provide a living body measuring device with a built-in weighing scale, which is more effective in that it is impossible to tear off the paper with important information, so that the person to be measured is always can read the message. Another object of the present invention is to provide a living body measuring device with a built-in weighing scale, wherein the person to be measured can easily confirm his position on the device, can easily see the display of the measurement result, and Faults are easy to spot when they fail.

To achieve these objects, the present invention provides a living body measuring device with a built-in weighing scale, which includes a measuring platform having a plurality of load cell assemblies for measuring the weight of a living body, and a plurality of electrodes, For measuring biological impedance, it is characterized in that the measurement platform has an inner plate and an outer plate formed by a transparent plate, a circuit board is installed in the inner plate, and the plurality of load sensor components are physically connected to the The inner plate on which the electrodes are arranged, the total area of the top surface of the load cell assembly and the inner plate is smaller than the top surface area of the outer plate, so that the paper can be attached to the measured The underside of the platform so that the paper can be seen through the measurement platform.

Correspondingly, a paper with important information can be attached on the lower surface of the outer panel, since it can still be seen from above through the transparent outer panel. In case the outer panel is a colorless transparent panel, the visibility of the information through the outer panel will be higher.

According to one embodiment of the invention, the measuring platform is constructed as a single-layer structure, which has only one outer plate which also functions as an inner plate. In this case, the internal structure of the device is visible from the outside through the transparent outer panel, without dismantling the device.

According to another embodiment of the invention, the electrodes on the outer plate are formed by an electrically conductive transparent coating. Thus, an area of the outer panel becomes wider through which a person can see its opposite. The above-mentioned area of the outer plate can become wider when the electrodes are formed of a conductive colorless transparent coating.

According to yet another embodiment of the present invention, protrusions are provided on the electrodes. Therefore, the person to be measured can accurately place his foot on the electrode while confirming its position with the feeling of the sole of his foot.

According to yet another embodiment of the present invention, the apparatus further includes a light emitting device housed in the cavity of the outer panel. Therefore, the light emitting device emits light through the display window frame to illuminate the display device.

According to yet another embodiment of the present invention, the apparatus further includes a plurality of light emitting devices and a light control device, whereby each of the light emitting devices emits light of different colors, and the light control device controls the light emitting devices to measure As a result, different colors of light are emitted. Therefore, the person to be measured can get a strong impression from the measurement result.

Detailed ways

1(a), 1(b) and 1(c) are external views showing a body fat measuring device with a built-in weight scale according to the present invention. More specifically, Fig. 1(a) is a plan view of the body fat measuring device, Fig. 1(b) is a side view thereof, and Fig. 1(c) is a front view thereof. The body fat measuring device with a built-in weighing scale 1 according to the present invention comprises a two-layered measuring platform having an annular inner panel 3 and a circular colorless and transparent outer panel 4 . The inner panel 3 has the load cell assembly 2 mounted directly thereon, and the load acts on it directly from the floor. The outer panel 4 is in direct contact with the person to be measured when it is on it. The outer panel 4 includes electrodes 5 for measuring the biological impedance of a person, and an input switch 6 for adjusting the personal condition or parameter used for the measurement.

The term "plate" as used herein refers to any flat plate including or excluding partial cutouts, grooves and protrusions, but excluding ribs. The colorless and transparent outer panel 4 is formed by injection molding of a colorless and transparent methyl methacrylate resin.

The electrodes 5 include a pair of power supply electrodes 5a for forming a current path in the living body and a pair of measuring electrodes 5b for detecting potential generated in the living body. Both the supply electrode 5 a and the measurement electrode 5 b are formed by an electrically conductive colorless transparent coating formed directly on the outer plate 4 . Conductive colorless transparent coatings are well known in the art and may be formed from physical or chemical coatings of tin oxide or indium oxide.

The power supply electrode 5 a and the measurement electrode 5 b are each provided with a hemispherical protrusion 9 which is formed at the time of resin molding of the outer plate 4 .

The electronic circuit board 11 housed in the cavity of the inner panel 3 includes a reflective liquid crystal display device 7 for displaying adjustment status and measurement results. The circuit board 11 further includes a light emitting device 8 and a combination of a well-known amplifier, A/D converter, arithmetic unit, storage unit and control unit for processing the detected load signal. In addition to the functions already known in the art, the control unit provides another function for controlling the lighting means. The lighting device 8 comprises a green-emitting diode 8a, a yellow-emitting diode 8b and a red-emitting diode 8c.

Fig. 2 is an enlarged sectional view of the device along line B-B in Fig. 1(a). It can be seen that the electronic circuit board 11 is housed in the cavity of the inner panel 3 . The circuit board 11 includes the reflective liquid crystal display device 7 mounted thereon in a position surrounded by the surface 10 forming the display window frame in the outer panel 4 . The circuit board 11 further comprises a green-emitting diode 8 a located in a cavity of the outer board 4 . For the sake of clarity, the diode 8b emitting yellow light, the diode 8c emitting red light, the amplifier, the A/D converter, the arithmetic unit, the storage unit and the control unit are omitted in FIG. 2 .

The power supply electrode 5a, the measurement electrode 5b, the load cell assembly 2, the input switch 6 and the electronic circuit board 11 are all connected to each other by wires to complete the whole device.

The body fat measuring device 1 with built-in weight scale is activated after personal parameters are set using the input switch 6 in a manner known in the art. The measurement results are displayed on the reflective liquid crystal display device 7 in such a manner that the body fat percentage and body weight are alternately displayed. At this time, if the body fat rate is within the normal range (for example, 14% to 23% for men and 17% to 27% for women), the control unit for the light emitting device will act to turn on the green light emitting diode 8a. If the body fat percentage corresponds to a slightly obese range (for example, 25% to less than 30% for men and 30% to less than 35% for women), the control unit turns on the yellow-emitting diode 8b. Also, if the body fat percentage corresponds to the obesity range (for example, over 30% for men and over 35% for women), the control unit turns on the red-emitting diode 8c.

In the body fat measuring device 1 according to the present invention, the outer panel 4 is a colorless and transparent panel formed of methyl methacrylate resin so that a person can see the opposite side of the outer panel 4 . Therefore, paper with important information such as precautions or operating instructions can be attached to the lower surface of the outer panel 4 . In this way, the situation that the person to be measured is unavoidably stepping on the paper with the sole of the foot for measurement as mentioned above is avoided. In addition, even if a person puts wet feet on the outer panel 4 after taking a bath, it is impossible to wet the paper, thereby preventing the paper from being torn off.

Since the electrodes 5 are formed directly on the outer panel 4 with a conductive colorless transparent coating, an area on the outer panel 4 becomes larger through which a person can see its opposite side. Consequently, the available facing area of the outer panel 4 also becomes larger. Therefore, the number or size of papers carrying important information such as precautions or operating instructions can be increased.

Since the protrusion 9 is formed on the electrode 5 , the person to be measured can confirm the exact position with the feeling of the sole of his foot when he is on the outer panel 4 . In addition, even after being placed on the outer panel 4, a person can confirm the exact position, so that accurate measurement can be realized.

Depending on the arrangement of the light-emitting diodes 8 a , 8 b and 8 c in the cavity of the outer panel 4 , the light emitted by these light-emitting diodes can be transmitted through the cavity of the outer panel 4 . The light is then transmitted through the surface 10 forming the display window frame to illuminate the reflective liquid crystal display device 7 . Therefore, even if the device is located in any dark place, it is easy to see the illuminated information on the display device 7 . In addition, the control unit turns on any one of the light-emitting diodes 8a, 8b, and 8c of different colors, and therefore, a person to be measured can get a strong impression of the measurement result. Thus, an obese person can perceive that he is obese after the measurement.

So far, the preferred embodiments of the present invention have been described, however, the present invention can be implemented in any other manner. For example, the outer plate 4 can be made of any colorless and transparent material such as glass or polystyrene resin, instead of being made of methyl methacrylate resin as mentioned above. Furthermore, any colored transparent material can be used with equally good effect, since visibility through the outer panel 4 is still obtained.

Equally, opposite electrode 5 also can adopt any conductive transparent coating and has equally good effect, instead of adopting conductive colorless transparent coating, because the people on the outer plate 4 can see its opposite wider through it. The region can still be maintained. The electrodes 5 can be modified in such a way that the conductive transparent coating is formed on any other transparent part to be mounted on the outer panel 4 instead of forming a transparent coating directly on the outer panel 4 as described above.

As another embodiment, the inner plate 3 can be omitted, and the load sensor assembly 2 can be directly installed on the transparent outer plate 4 to form a single-layer structure. According to this structure, the internal structure of the device can be seen from the outside through the transparent outer panel without disassembling the device. Thus, any disconnection of wires or other defects can be easily found without dismantling the device.

The protrusions 9 on the electrodes can be protrusions of any shape, such as any letters or numbers, instead of the hemispherical shape as described above. Alternatively, instead of having the protrusions 9 molded with the outer plate 4, a separate protrusion part could be made and attached to the electrode 5.

The colors of the light emitting device 8 are not limited to red, yellow and green, but any other colors may be used. Also, any other light emitting device may be used instead of light emitting diodes.

The present invention has been described above with reference to a body fat measuring device with a built-in scale, but the present invention is not limited to such an embodiment. For example, the present invention can be equally applied to a body moisture measuring device with a built-in weight meter that includes electrodes for measuring the impedance of a living body, or to a pulse meter with a built-in weight meter.

From the foregoing, it is obvious that by making the outer panel transparent, the paper with precautions and operating instructions can be attached to the rear surface of the outer panel, since they can still be seen through the transparent outer panel. In this way, the inevitable tendency of the person to be measured to step on the paper with the sole of his foot in order to measure is avoided. Furthermore, if a person puts his wet feet on the outer panel after taking a bath, it is impossible to wet the paper, thereby preventing the paper from being torn off. Also, by forming the outer plate with a colorless and transparent plate and forming the electrodes with a conductive transparent coating or a conductive colorless and transparent coating, high visibility can be obtained through the outer plate, so that the relatively small size of the outer plate can be effectively utilized. wide area. This greatly increases the usefulness of the device.

Furthermore, by forming protrusions on the electrodes, the person to be measured can confirm his position with the feeling of the soles of his feet while he is on the outer plate. Therefore, even after being positioned on the outer plate, a person can accurately stand on the electrodes, which can contribute to accurate measurement. By placing the light emitting device in the cavity of the outer panel, the emitted light can thereby be transmitted through the surface forming the display window frame to illuminate the reflective liquid crystal display device. Therefore, the information on the display means can be easily seen even if the device is located in any dark place. Furthermore, since the control unit operates one of the light emitting devices of different colors, the person to be measured can get a strong impression of the measurement result. In particular, an obese person can perceive that he is obese after the measurement. Finally, by forming a single-layer structure with only the outer panels, the inner structure of the device can be seen from the outside without the need for disassembly. Therefore, any failure or malfunction in the device can be easily found without having to disassemble the device. These features of the present invention greatly increase the effectiveness of the device.
